A chemist has 500g of a solution that is 40% acid.
\n" ); document.write( " How many grams of water must be added to reduce the acidity to 25%?
\n" ); document.write( ";
\n" ); document.write( "Let x = amt of water required to accomplish this
\n" ); document.write( "A simple equation
\n" ); document.write( ":
\n" ); document.write( ".40(500) = .25(x+500)
\n" ); document.write( "200 = .25x + 125
\n" ); document.write( "200 - 125 = .25x
\n" ); document.write( "75 = .25x
\n" ); document.write( "x = \"75%2F.25\"
\n" ); document.write( "x = 300 grams of water required
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( "Check, amt of acid should be equal
\n" ); document.write( ".40(500) = .25(300+500)
\n" ); document.write( "200 = 200
\n" ); document.write( "
\n" );
